The article Healthchecks.io Hosting Setup, 2022 Edition was recently on Hacker News. I was answering questions in the comments section. Here’s a recap of some of the questions and my answers. I’ve edited some of the questions for clarity.

So far in this series, you have learned why it’s important to understand how to use the command line, some command line basics and shell commands, and all about running CLI-based applications and command line tools.

Calico v3.23 is out, and with it a lot of new features! This release marks a long-awaited milestone for me and my team, as it includes the Calico VPP data plane (beta). So now seems to be a good time to reflect on what this integration actually is, and why we built it.

It’s funny how even today, in 2022, people still ask me if WordPress is a good choice for a high-traffic website. There are few website-building solutions on the internet as tested as WordPress.

As a result, you as an individual or organization using it for your business are responsible for monitoring your WordPress site.

At this point in my career, I’ve realized the responsibilities of database administrators (DBAs) and database reliability engineers (DBREs) can differ from company to company, from year to year, and even from quarter to quarter.

Site Reliability Engineers (SREs) have a considerable set of tasks to juggle no matter where they work or how long their company has had an SRE practice.

You may find it difficult to get buy-in for SRE from other technical teams.

Having trouble deploying Kubernetes in a highly available mode and have a backing remote database? This blog is for you. I will explain how to deploy K3s in HA configuration with an external database Postgres. K3s is a certified Kubernetes distribution for IoT and Edge computing.

It is an exciting time to be a startup. Our vast technological landscape has made powerful digital tools available to businesses of all sizes, making starting (and scaling) an organization easier than ever before. In an era where technology is a fundamental building block of almost every business, methodologies like DevOps have become ubiquitous across many industries.

To keep ahead of the curve, many organizations are looking at how to evolve their technical processes to accelerate their IT infrastructure development. Fast and robust deployments to the latest platforms are key to achieving the low lead times that enable this evolution. Two of the most widely-used technologies to host these deployments are serverless functions and containers. What are they, how do they differ, and how do you decide which is best for your application?
